Thus in Fig. 1 the rail is shown shifted to its position to the rightjthe lowest face, 0, of the'right hand "clamp engaging the rail base, while the top facea. of the left hand clamp engages said base. When the rail is positioned centrally of the rail base,

"the "faces bof both'clampsengage' the rail base. When the rail is shifted toits position to the left, the lowest face of the left hand clamp and the topface of the right hand .;clamp engage the rail base. wedge character of the key D, thehead may Owing to the bexas firmly forced against the rail base whatever position'the clamp may be caused to assume. a 1 i i The correspondence between the contour of the clamp and itsseat 7 maintains a per-. fect. bearing at all times for the body of the" clamp and the strain and tension-are readily tie without undue strain upon the clamp orthe walls of the seat. 7. The projection forms the fulcrum. The curved form ofv the seatand the clamp bodyxenables the :clamp' to .be' ti ghtened snugly: against the 4 through the other. aperture, and a-,second member bearing against thetop'of said tie and eXerting-an upward tension on saidtail.

In railway devices'for'the-purposedescribed, the combination of an I-be'am cross- .rail base without difficulty.

To insulate the rail, so tiat it may be used as part of a signal circuit, I provide a mat '12, of hard insulating material, such as fiber, which is interposed between the .rail

platform a and the rail base, as shown.

Such mat is provided withjintegral ears 13; which fit on either side of the he'ads'of the clamps Gand thus hold-thematagainst displacement. To 1 insulate the rail; from r the fasteners, an L-shaped insulating member 14, of-izsimilar material to that of mat 12,)is used: The. laterally" extended head 15 of saidmem-ber 14 is interposed between; the rail base and the face of the head which is I to be clamped against the'formenwhile the depending legs, 16, of the member :14: extend downwardly through the; elongated portion of the aperture 5 into the recessed,

portion 8 of the-seat 7.- I To prevent possible contact between the web 2 of the tie and the lower end of the member 14:, the depending legs 16 of the latter are preferably bifurcated as shown to straddle said web.*

a It is evident from the foregoing that my invention provides inexpensive, yet durable and effective means for securing a rail to a cross-tie, which will permit of ready gage adjustment and perfect insulation of the rail; The contact between the clamps and the rail is always positive and will not loosen u-nles's the wedge key is intentionally contractedhy means of a suitable tool and the wed e driven back in the slot 10. The clamp, liowever, is readily and easily installed, removed or adjusted to allow change in gage.
